## Long description

The Koss Porta Pro is a wired supra-aural headphone designed for personal and portable listening. Introduced in 1984 and preserved in its original form, the Porta Pro delivers a wide frequency response of 15–25,000 Hz, lightweight construction and a 1.2 m cable for everyday use. Its mylar dynamic elements, neodymium magnets and oxygen-free copper voice coils are engineered to reproduce clear, accurate sound with pronounced bass and sufficient volume for noisy environments. Foam ear cushions provide an open, hear-through experience while keeping the headphones comfortable for travel, commuting and active use.

Its lightweight build and supra-aural fit make it easy to wear for extended periods, and the 1.2 m wired connection offers reliable playback without battery dependence. Available in black and silver, the model balances portability, comfort and sound clarity for everyday listening.

How to use
Connect the 3.5 mm plug to your audio device and place the supra-aural pads over your ears. Adjust the headband for a comfortable fit so the foam ear cushions sit lightly on the ears to allow some ambient sound through. Use device volume controls to set listening level; the Porta Pro's neodymium magnets provide sufficient output for typical portable players. When not in use, fold or store the headphones in a protective case or pouch to prevent cable damage.
Usage recommendations
For best performance, avoid exposing the headphones to moisture and extreme temperatures. Clean the foam ear cushions gently with a dry cloth and disconnect the cable from the source when storing. If using in noisy environments, increase device volume moderately to preserve audio detail without risking hearing discomfort.
